This paper focus on energy efficient driving strategy for MRT trains. In MRT systems, Automatic Train Operation (ATO) has been widely used. The calculation of a reference trajectory seems more important, since it could improve the performance of ATO. The operation demands for MRT trains are different from freight trains, such as energy saving demand and the characteristic of traction. In this paper, based on the characteristic of traction and some results got by the former researchers, a new energy efficient strategy model is proposed by using nonlinear programming method. It is the first time to combine the analytical and numerical method together in this area. By applying the new method, it is unnecessary to pre-given any key value. Moreover, since it is easy to solve, it could be used in real-time operation adjustment. The feasibility and effectiveness are verified through simulation. Compared the simulation results with the actual operating data, our new method are efficient on energy saving with the guarantee of punctuality.
